Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971890, here are decompositions:

  • 107 + 971783 = 971890
  • 131 + 971759 = 971890
  • 137 + 971753 = 971890
  • 167 + 971723 = 971890
  • 191 + 971699 = 971890
  • 197 + 971693 = 971890
  • 239 + 971651 = 971890
  • 251 + 971639 = 971890

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 971,890 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 971890 first appears in π at position 168,180 of the decimal expansion (the 168,180ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
